boing observed on the VFNR-13, Nami (Charlie) Island ini the skiffs
lying in the northwest quadrant.
Surface readincs of samples collected
on islani, raft ani barge stations averaged 50 mr/hr at 1490 on N #1
day, with some as hich as 290 mrfhr at the same time.
The time of ar-
rival of fallout ct the YFNR-29 was about 17 minutes and 15 minutes at
Zath
profcet ship reecived fallout, the eaprroximate time of errival
betne 4 # 2.9 hourc for the VAG-39, H # 2.2 h-urs for the LST-+S11 and
# €.5 hours for the YAG-49,
The highest activity level observel was
avproximitely 1.3 rfir at atout H # 4.4 hours on the deck of the VAGH29y
eats
while the
maximum 2cek intensity cbserved on the YAG-19 was 115 me/hr
formed at early times
in the shielijej] laboratory abcard the YAC-240,
The great majority cf those data are being reduced at the present time.
Tt appears hewever, that the primary fallcut arviveil in slurry droplet
similar to that observed for event Plathead.
nce again the droplets
Oo
averaged 19C to 2% microns in diameter, ordinarily possessed an NaCl
content greather than 80 porecent, and appearcd te contain smaller
particulate with which nearly ell of the activity was associated,
The data obtained are being cvaminc? further and additional analyses
are being performed at NADL; these results will he included in the
preliminary report.
